- Graphics acceleration: One Logisim user observed that adding `-Dsun.java2d.d3d=True` to the command line seemed to improve Logisim's graphics performance by telling it to use hardware graphics acceleration. This drop-down box attempts to configure Logisim to set this up; reports about whether this drop-down box has any effect on performance would be welcome. It won't have any effect until Logisim is restarted.

Next: Command line options.
